This should be particularly interesting since I know hw many of us study fr the sake of marks nd hw many study "Dil se".
Conventional concrete suffers from a number of problems such as low tensile strength and a tendency to shrink as it sets. It is also brittle, which makes it liable to fail suddenly.
Recently a team from Univ of Florida have discovered a glue that binds concrete mix tightly.
The glue, a form of polyvinyl acetate, ensures that any cracks propagate slowly, making the concrete far more ductile ??? like a metal ??? so that it fails more slowly. That should give more time to take action when a concrete structure starts to crack. The additive also reduces the amount of shrinkage that concrete undergoes when it dries.
